Incorporating JavaScript into an Application
Adding JavaScript to a Web application is a great way to add features that mimic those found in client/server applications without sacrificing all the benefits of Web deployment. Oracle Application Express includes multiple built-in interfaces especially designed for adding JavaScript.
Remember that JavaScript is not appropriate for data intensive validations. For example, to verify that a name is contained within a large database table, you would need to pull down every record to the client, creating a huge HTML document. In general, complex operations are much better suited for server-side Application Express validations instead of JavaScript.
